through a shifter system including a lever engaged at one end with the driver and at the other end connected bya link with a treadle." ()ne object of this invention is toprovide means whereby when a predetermined yardage has been wound on the reel the shiftor system may be rendered, preferably automatically, impotent or inoperative to bring the driver into or hold it in' driving engage tlve) Wlll keep the reel rotating;

ment with the reel, whereby the'reel cannot be re-started and the yardage predetermined cannot thus be unwittingly exceeded until'at I least'the operator has performed a'resetti'ng operation. When effected automatically, this is accomplished by a part which moves'with the reel encountering another part'to move 7 the same and cause the shifter means to be rendered inactive as stated. Usually, either subjectto the operator or automatic means, the'cutting off of the power in this way will be practically instantaneously accompanied by a braking and stopping of the reel; wherefore, given means also included in the invention to re-establish the shifter system in operative state, another object is to construct ders inactive when said system is in the position where the driver is held in' driving engagement with the reel; and a further object is, if the machine is equipped withmeans to lock said system in the position fordriving the reel and therefore for maintaining the brake inactive, to construct the mechanism so that when said system is autom'ati Y cally rendered impotent or inoperative in the respectshereinbefore stated said system will be unlocked or released so that the brake will be set Inthese mathe principal parts concerned in the invene In the drawings, I I r Fig. 1 is a side elevation of a warping machine embodying the invention; 7

known supporting means for the same. 5 is a sprocket-and-chain connection whereby from the reel a screw-shaft 6 for effecting the traverse, parallel with the reel-axis, of the usual reed-carriage (not shown) is rotated. 7 is the mentioned driver rotated from any source by a belt 8 and normally by its weight held depressed and clear of the rim 2 but adapted to be raised to engage said rim, being here as usual journaled in a pivoted bracket 9. r

The shifter system here includes an actuated member, an actuating member and a toggle connection between them. The ac- 3 is a brake-strapv 'engagingthe rim 2'? of the reel and 4, 4-?

tuated'member is a'lever 1O fulcrumedbe tween its ends, one'end supporting the driver. The actuatinginember is here apitman 11 having a crook-like upper end and having a treadle 12 pivoted to its lower end and fulcrumed inthe frame. and further having means'to limit its upward and downward movement, one of which is frame 1 with which a lug 13 911 th treadle is held engaged under the influence of a spring 1% connecting the t-readle with the frame and the other of which is a stud 16 on the frame with which the upper end of a. slot 15 in the pit-man is adapted to engage (Figs. 4 and 8) under a condition-to be stated. The said toggle connection includes links 17 within the crook of the pitman and pivoted together at 18, having theirrouter ends pivoted to the pitmanand the lever, and having stops 1'17 and 17 which. in the extended condition of the toggle engage each other (Fig. 4E) the toggle being adapted to be broken or buckled by application of force against the same from the right in Fig. a and bet een the pivots Where the connection'is joined to' the lever and .pitman (a hump 11 on the pitman crook may limit the buckling movement) 7, a spring 19 connects the crook of the pitman with the lever and tends to maintainthe toggle connection in either its extended or buckled condition. 1

When the shifter system is normal e., its said connection being in extended state), under the pull of spring 14 and the weight of the driver it tends to stand in the fullline position shown by Fig. 8 or againstthe stop 1, the driver being then so spaced from ri1n2' that on depressing the pit-man the driver will encounter the rim before stop 15 encounters stud 16,. andso the reel will be driven. But if the system be collapsed by breaking the toggle the driver will. assume the dotted line position; if this happens when it is being held by the system in contact with j the rim it will clear it, so that the reel will cease to be driven, and if it happens when it is not incontact therewith (as when the driver is retracted, or not driving the reel,

but the operator, as occasionally happens, should be turning the reel directly by hand) depressing the pitman in the effort to cause portion already wound or introduce some marker, the inoperative state of the shifter system prevents further reeling by resortto the shifter system untilsaid system has been reset. 7 Y

It is known to employ a chock to holdiu active position a movable man-operated shifter system for a-driver (as 7'), as where said system comprises a lever (as 10 a treadle (as12) and a. simple linkconnecting the lever and treadle,

in the use of these machines which chock the operator removes when the driving is to cease. According to one aspect of the invention it is not a matter of introducing a chock between such system and some support, as the frame, but of making said system itself collapsible, whereby when said system is'in one of its collapsed and extended states it would hold the driver further from the reel than when said system is in its other state; in the present and preferred sp'ccies of the invention said systemis normally adapted to assume one of said states but releasably held thereagainst and when in such state it holds the driver further from said reel than when in the other state.

While, with notice obtained in some way that the winding has proceeded to a predetermined extent, the operator might by hand render said system thus inoperative to restart the reel so that its inoperative state would remain a reminder to attend to the matter requiring attention, I prefer to accomplish this automatically by tripping means: The frame includes a standard 1 on a stud 20 of which is j ournaled a. dial 21 which is driven by the reel through ashaft 22 which at one end is connected with shaft 6 bybevel gearing 28 and at the other end has a worm 24 meshing with worm-teeth on the dial. It will suffice to note that the dial has a stud or projection 25 which may be set, fixed thereto, at some position in a circle concentric. therewith A push-rod 26 affording a knock-off member is confined to slide lengthwise inthe end of'an arm 27 and is'connected by a bell-crank lever 28 wlth a link 29 which is connected with the pivot 18 of the toggle-links. When the toggle is extended a roller 265011 member 26projects into the path of the stud 25, wherefore when the reel turns the dial around until this stud encounters said roller the consequent displacement of said member will cause the toggle to be broken, or the collapse of the shifter system.

LUZ;

In a certain aspect the to gle connection 1? acts as a withdrawable ho ding means or chock.for instance, when the operator holding the link down (or has locked it down as will hereinafter appear) and consequently secured the. lever in the position where the driver is against the ree lin which case the link 11 afiords the support for the chock. As

already indicated the use of withdraw-able.

.here also of the toggle (since they are connected at 18 and form in effect a mechanism movable as a unit) may be accomplished by a lever 30 fulcrumed in the frame and having a handle 30? upstanding in convenient reach when the operator is in position to start the reel by depressing treadle 12' and also having acam arm 30 to wipe againsta stud V 28? on the bell-crank lever 28 whenthe handle is shifted to the right was it appears in Fig. 3 (this lever, by the weight of the handleand cam arm, is-normally held to, the left, bearing againstmember 22). As will appear a device (as normally tends to press on brake-band 3 tostop the reel, being however retracted whenever the treadleis depressed; the treadle will usually be released at once on breaking of the toggle (by the operator, if

lie-is holding" the treadle'down, as soon as he senses the break in the toggle, or by release of the treadle automatically if it is locked.

down as hereinafter stated), and this will leave the stud usually ina position precisely 7 be shifted to the left as'an mcident of the resetting operation-by a cam 32 on an arm 32 of lever 30 when-the latter is shifted to reset the toggle, so that as thepush-rod rises in the resetting it is displaced to the left and its roller therefore rises relatively back and thus clear ofthe stud 25.

I ,The brake afforded by band 3 is so controlled that it' is off when the reel is driven and on when the driver is withdrawn from the reel rim. Thus, as in'my application Serial No. 317,650, there may be-a lever 33 suitably fulcrumed on a structure 34 in effect forming afiXed part of theframe and normally urged against the brake-band3 by a I spring 35 but adaptedto be retracted by having its'dependingarm 33* connected with a link :36 which has an abutment at 36%in the path of movement, when the treadle is depressed, of a staff-like crank 37 upstanding rigidly from-the treadlelQ, so that lever 33 to start the reel. a

is withdrawn when the treadle is depressed v 7 here may also be means to lock the treadle down so that theoperator can leave the machine running alone, such means here being the same as in mysaid application and comprising (Fig. 4:) a hand bar 38 revoluble in thefram'eand having a crank 39 which isone element of a toggle connection between said shaft/and the treadle, the other element of which is a link d0 which is pivoted to the crank at 4:0 and has a slot 40* (Fig.

1) receiving-a stud 12 on the treadle,the upper end of'the link projecting upwardly beyond pivot 40 and forming a hunter to impinge against the shaft when the shaft has beenturned anti-clockwise in Fig. 4, or until pivot 40 has passed a plane coinciding with the axis of the shaft and pivot 12 (Fig. 3). With the machine so equipped, there should be means to cause collapse of this toggle-lock for the treadle whenthe toggle lock for the shifter means is collapsed, else the described connection between the treadle and lever 33 will not be released to apply the brake. Hence, a link f1 isconnecte'd to the pivot 4:0 and has a slot 41 receiving the pivot 18 of the toggle-links 17, and when the treadle lever is toggle-locked down. theforward end of this slot is positioned so as to be engaged by the pivot 18 when the toggle-lock 17 is broken which acts throughthe link to break or collapse the treadle-lever toggle-lock. A slot '1 ll is present instead of a hole in the-link so that the treadle-lever toggle-lock may be manipulated idly with respect to the other toggle-lock when the latter is normal or extended, and it is so formed that when the treadlelever toggle-lock is operated to lock down the treadle it willnot establish the toggle-lock at 17 (note the space in Fig. 4 between pivot 18 and the left-hand end of the slot) else theoperator would haveitin hispower to reestab lish the shiftersystem as an incident of the usual movement for starting the reel, as in the case where,as by perchance having rotated the reelsomewhat byhand,the dial stud .25 was made to pass the push-rod and so no 1 longer remained an obstacle to such re-establishment of the shifter system.
